To all whom, it may concern:
Be it known that 1, ERNEST V. Acnnson, a citizen of the United States of America, and aresident of Salt Lake City, SaltLake county, Utah, have invented certain new and useful Tmprovelnents in Umbilical Forceps and Metal Sealing-Bands, of which the following is a specification.
My invention contemplates an improved pair of umbilical forceps of that particular character in which the cutting of the umbilical cord and sealing the same by metallic process by the application of metal sealingbands to the ends of the cord are accomplished in one manipulation of the instrument.
In the accompanying drawings, Figure 1 is an enlarged side elevation of my improved instrument with the jaws closed and showing the handles broken away for convenience of illustration; Fig. 2, a vertical section on line 2 2 in Fig. 1; Fig. 3, a plan of the instrument shown in Fig. 1; Fig. 4L, a vertical section on line A 4 in Fie'. 1; Fig. 5, adetail section on line 5 5 in Fig. 3; Fig. 6, a front or end view of one side of the instrument shown in Fig. 1; Fig. 7, a view similar to Eig. 1, but showing the jaws separated and the metal sealing-bands in position to be applied to the cord; Fig. 8, a view similar to Fig. 7, but showing the position of the jaws and parts after the severingl of the cord and the application of the clamping-bands; Fig. 9, a fullsize view of one of the upper clamping-jaws; Fig. 10, a fullsize view of one of the campin and needle carrying' plates; Fig. 11, a fullsize view of one of the lower clamping-jaws; Fig. 12, a section on line 12 12 in Fig. 10, and Fig. 13 a full-size perspective of one of the metal sealing-bands- As thus illustrated, my improved pair of umbilical forceps comprises a pair of handles A and B, pivotally connected by a pivot-pin C and provided with cutting-blades o and The said blades are provided with openings a and b', and in these openings the cylindrical cross-heads D and E are inserted, said crossheads being formed with reduced end portions of CZ and c e. As shown, the pivot-pin is formed with reduced end portions c and c and also with an annular groove In this way the handles are pivotally connected by the middle portion of the pin C, and the crossheads D and E are carried, respectively, by the blades and c. The sealing-clamps E and (r arel mounted at opposite sides of the cutting-blades and are operated by the latter when the handles are opened and closed, the jaws of said clamps being' carried on the re duced end portions of the cross-heads and pivotally connected by the reduced end portions of the pivot-pin. For example, the clamp F comprises the upper and lower jaws f and f, having openings f2 and f for the pivot-pin and having also cam-slotsfi and fr. It will also be seen that the jaw f has a notched openingfIG and a pair of prongs f7, while the jaw f/ is provided with a notched openingj-as and three prongs f". Also, as illustrated, the jaw f is formed with slightly-separated disk-like portions fw, and the jaw f is formed with similar disk-like portionsfu, the portionsfu fitting' and working between the portions fw. Each jaw can be made in one piece; but it is constructed from iive superimposed plates which are fastened together by rivets, as shown. The plate f 1provided with the necdle fm and the cam-pin f and having the slot fl, fits and works between the portions/ Keys Z2 and c2, provided with notches, are secured in the end portions d and c and adapted to engage the notches of the openings f and f8. Split or notched lockingrings (Z3 and c encircle the portions d' and e and engage the notches in the keys Z2 and @2. 1VV ith this provision it is obvious that the jaws cannot be removed from the cross-heads until the rings d and c are rotated suliiciently to bring their notches into register with the said keys. The said rings are mounted between the plates of which the jaws are composed and are provided with roughened edges to facilitate their rotation. A spring-key H, having a hook-shaped portion t, adapted to engage the groove c in the pivot-pin, and provided with an opening in its other end adapted to engage the small pin or projection it on the handle B, serves as the means for holding the blades together.
With this arrangement the handle A is secured to the pivot-pin C, while the handle B is loosely mounted thereon. By disengag'ing the flexible key from the pin /L its hook-shaped end can be withdrawn from the groove c2, so as to leave the handles free to separate. It will be understood that the clamp G is in all respects the same as the clamp F. When the instrument is closed, as shown in Fig. 1, the prongs of t ie upper jaws interlock with the prongs of the lower jaws, as shown in Fig. 6. At such times the pivot-pin is at the inner end of the slots in the plate f 12 and the corresponding plate of the clamp G. Also when the jaws are closed the needles on these plates project between the jaws and the campins are at the `inner ends of the cam-slots in the interlocking pivotally-connected portions of the jaws.
In use the metal sealing-bands I, each in the nature of a split ring or band having a small hole e' adapted to receive one of the needles, are first placed in position, as shown in Fig. 7. The handles are then brought together, so as to cause the edges of the cutting-blades to pass each other and so as to compress the sealing'- bands near the ends of the severed oord. This closing' of the instrument causes the cam-slots in the disks to act on the cam-pins in such manner as to keep the needles inserted th rough the openings in the bands. Upon opening' the instrument, however, the extreme separation of the handles causes the said cam-slots to act on the cam-pins in such manner as to shift the two plates bearing the needles to the position shown in Fig. 8, thereby withdrawing the needles from the bands. Thus the needles when the cord is cut are allowed to remain in position to keep the ends of the cord from slipping' away until after the sealing-bands are properly applied. These sealing-bands are preferably flat in character and of any suitable metal-for example, aluminium.
With the provision of the cross-head having keys and locking-rings it is obvious that the jaws can be easily and quickly removed, thus facilitating' cleaning and sterilizing' and the taking apart and assembling of the various portions of the instrument; but notwithstanding the readiness with which the instrument can be taken apart and put together it will be seen that the instrument is strong and rigid and that the construction is of such character as to prevent any yielding or slight displacement of the parts during the delicate operation of severing and sealing the cord. Furthermore, the sealing-bands can be clamped down fiat upon the cord, thus effectively sealing the ends of the latter.
